Suppose you ran the following regression and found this statistically significant result: AGE = 120 + -4*HEALTH where AGE is how old someone is and HEALTH is a rating on how healthy they are, from 1 (very unhealthy) to 20 (very healthy). You realize you have it backwards: age causes health, not health causes age. What should the new equation be? 1 HEALTH = -30 + -0.25*AGE 2 It is impossible
